Description:
on my H7, i get 0b0010110 for first byte.
on my H10, i get 0b0010000 for first byte. (sensor contact statuss bit and sensor contact support bit are 0)

why is skin contact sensor not supported on newer model H10 when it was supported on H7?
is there perhaps something i can do to enable sensor contact support on H10? it works well on my H7.

(also, out of curiousity, does sensor skin contact support work on H9? i do not have this device to test, and i want two bluetooth connections anyway, which the H9 does not support)
